“…Our finding confirms the intensification of the global water cycle as the Earth gets warmer (Markonis et al., 2019). The upward trend of temperature over LP was more than twice as high as that over the global land area (Tian et al., 2022). Global warming causes more water from the land surface to be transported to the atmosphere (Huntington et al., 2018; Nogueira, 2019), given the Clausius‐Clapeyron relationship between atmospheric moisture and temperature.…”

Afforestation is regarded as the most appropriate approach to control soil erosion (Jia et al., 2017;Porto et al., 2009), but expanding vegetation needs more water to maintain its growth (Huang et al., 2020;Teuling et al., 2019;Q. Wang et al., 2021). Precipitation thus plays a crucial role in the sustainability of afforestation, especially for water-limited areas. Atmospheric moisture is of great relevance to precipitation generation (Payne et al., 2020). There are two sources for atmospheric moisture overlying a land area: the first is external moisture flowing into this area by horizontal advection and the second is internal moisture provided by the local evapotranspiration (ET) (Y. Zhao & Zhou, 2021). The ratio of precipitation transformed from internal recycled moisture to the total precipitation received by this area is defined as the precipitation recycling ratio (PRR) (Holgate et al., 2020), which can serve as an indicator of the intensity of the water cycle (Gao et al., 2020;Trenberth, 1999). Both anthropogenic activities and climate variability affect the transport of atmospheric moisture and its transformation to precipitation (Baudena et al., 2021;Tuinenburg & Staal, 2020). To design science-informed and sustainable policies for afforestation, there is a growing need to explore the response of the atmospheric water cycle to afforestation and climate change.Afforestation alters moisture and energy fluxes interchanged between the atmosphere and land surface by affecting surface characteristics (Baudena et al., 2021;Hagos et al., 2014;. The Loess Plateau (LP) in China is an ideal platform to study the impact of large-scale afforestation on the atmospheric water cycle, since it launched the world's largest afforestation program (Cao et al., 2019), the Grain for Green Program (GFGP) in 1999. With an investment of US$54.57 billion (Bryan et al., 2018), the GFGP has led to a 57% decline

“…The regional climate of the LP has experienced warming (0.04°C yr −1 ) and wetting trends (4.48 mm yr −1 ; Li et al., 2019; Tian et al., 2022). Climate change can affect the atmospheric moisture inflow and outflow and atmospheric conditions of precipitation generation over land (Tuinenburg & Staal, 2020).…”

“…This data set combines MODIS daily data, monthly data, and meteorological station data to eliminate the missing and low‐quality MODIS values by co‐locating in situ observations, geographically weighted regression method, and regression of the elevation–temperature gradient. The reconstructed LST remote sensing data set has been widely used to analyze the spatiotemporal variations of LST (Amantai & Ding, 2021; Tang et al., 2022) and validate the performance of regional climate model (Tian, Zhang, Wang, et al., 2022; Zhang et al., 2022) due to its high quality.

The Tibetan Plateau (TP) is known as the "Third Pole" with average elevation of more than 4, 000 m above sea level (Qiu, 2008). The large uplift of TP forms source of mechanical forcing into the free atmosphere and influences the upper airflow across the Eurasian continent (Molnar et al., 2010;Son et al., 2019;Yuan et al., 2023). Meanwhile, large amount of incoming solar radiation absorbed by plateau surface in daytime induced strong thermal effect, directly heating the middle of troposphere above it (

“…GVF and LAI play a key role in partitioning canopy transpiration and soil evaporation, and albedo is important in determining the energy distribution at the land surface (Ingwersen et al., 2011; Yin et al., 2016). Previous studies have demonstrated that such default surface data unrealistically represents the actual vegetation conditions in the APENC (Tian et al., 2022; X. Wang et al., 2020; B. Zhang et al., 2021). Thus, we first updated the default land use and land cover map, LAI, albedo, and GVF in the WRF‐tagging model using satellite observations.…”

Land use and land cover change (LUCC) can influence the regional atmospheric water budget. In this study, the Weather Research and Forecasting model embedded with evapotranspiration (ET)‐tagging (WRF‐tagging) is used to investigate the atmospheric pathways of ET as well as where and to what extent ET returns as precipitation (P) in the agro‐pastoral ecotone of northern China (APENC). First, we updated the default land use and vegetation indices in the WRF‐tagging with high‐resolution and real‐time datasets. WRF‐tagging modeling reproduces the spatial distribution of P and ET reasonably after updating surface characteristics. Second, we analyzed and quantified the contribution of ET to atmospheric moisture and regional P in the APENC. The water vapor originating as ET is advected in the atmosphere below 600 hPa to hundreds of kilometers by the prevailing winds. Moisture recycling shows that 5.83% of P comes from local ET during the growing season in the core region of the APENC. Furthermore, to quantify the impact of LUCC on moisture recycling, we designed two different vegetation scenarios (Afforestation and Degradation) by changing land use and vegetation indices in the model. Results show that the precipitation recycling ratio increased to 6.31% in the Afforestation scenario, and decreased to 5.19% in the Degradation scenario, demonstrating the non‐neglectable positive feedback of vegetation on P. An analysis of land surface‐precipitation feedback processes indicates that the LUCC‐induced change in precipitation efficiency dominates P changes. Our findings highlight the importance of LUCC on local and regional moisture recycling in the APENC.
